Shimano Dura-Ace Di2 EW90 Junction-A Box

The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts.

Features:

  • This junction A is required to connect the shifters via E-tube wires to the down tube junction wire
  • 5-port design, one for down tube wire to bottom bracket junction, four for shifter connection. Ideally suited for TT/triathlon with multiple shifter positions
  • Battery level indicator feature
  • E-tube EW-SD50 wires not included
  • Additional charging point when using internal battery
  • Gear index setup switch to allow fine tuning via shifter buttons
  • Reliable and secure water resistant connectors
  • Stem mounting strap included

A 2 year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).
